Pull rdma updates from Jason Gunthorpe:
"Doug and I are at a conference next week so if another PR is sent I
expect it to only be bug fixes. Parav noted yesterday that there are
some fringe case behavior changes in his work that he would like to
fix, and I see that Intel has a number of rc looking patches for HFI1
they posted yesterday.
Parav is again the biggest contributor by patch count with his ongoing
work to enable container support in the RDMA stack, followed by Leon
doing syzkaller inspired cleanups, though most of the actual fixing
went to RC.
There is one uncomfortable series here fixing the user ABI to actually
work as intended in 32 bit mode. There are lots of notes in the commit
messages, but the basic summary is we don't think there is an actual
32 bit kernel user of drivers/infiniband for several good reasons.
However we are seeing people want to use a 32 bit user space with 64
bit kernel, which didn't completely work today. So in fixing it we
required a 32 bit rxe user to upgrade their userspace. rxe users are
still already quite rare and we think a 32 bit one is non-existing.
- Fix RDMA uapi headers to actually compile in userspace and be more
complete
- Three shared with netdev pull requests from Mellanox:
* 7 patches, mostly to net with 1 IB related one at the back).
This series addresses an IRQ performance issue (patch 1),
cleanups related to the fix for the IRQ performance problem
(patches 2-6), and then extends the fragmented completion queue
support that already exists in the net side of the driver to the
ib side of the driver (patch 7).
* Mostly IB, with 5 patches to net that are needed to support the
remaining 10 patches to the IB subsystem. This series extends
the current 'representor' framework when the mlx5 driver is in
switchdev mode from being a netdev only construct to being a
netdev/IB dev construct. The IB dev is limited to raw Eth queue
pairs only, but by having an IB dev of this type attached to the
representor for a switchdev port, it enables DPDK to work on the
switchdev device.
* All net related, but needed as infrastructure for the rdma
driver
- Updates for the hns, i40iw, bnxt_re, cxgb3, cxgb4, hns drivers
- SRP performance updates
- IB uverbs write path cleanup patch series from Leon
- Add RDMA_CM support to ib_srpt. This is disabled by default. Users
need to set the port for ib_srpt to listen on in configfs in order
for it to be enabled
(/sys/kernel/config/target/srpt/discovery_auth/rdma_cm_port)
- TSO and Scatter FCS support in mlx4
- Refactor of modify_qp routine to resolve problems seen while
working on new code that is forthcoming
- More refactoring and updates of RDMA CM for containers support from
Parav
- mlx5 'fine grained packet pacing', 'ipsec offload' and 'device
memory' user API features
- Infrastructure updates for the new IOCTL interface, based on
increased usage
- ABI compatibility bug fixes to fully support 32 bit userspace on 64
bit kernel as was originally intended. See the commit messages for
extensive details
- Syzkaller bugs and code cleanups motivated by them"
